The Zoo of Isolated Neutron Stars

open access: yesUniverse, 2023
In this brief review, I summarize our basic knowledge about different types of isolated neutron stars. I discuss radio pulsars, central compact objects in supernova remnants, magnetars, nearby cooling neutron stars (also known as the magnificent seven ...

R-Process with Magnetized Nuclei at Dynamo-Explosive Supernovae and Neutron Star Mergers

open access: yesUniverse, 2021
Nucleosynthesis at latge magnetic induction levels relevant to core-collapse supernovae and neutron star mergers is considered. For respective magnetic fields of a strength up to ten teratesla, atomic nuclei exhibit a linear magnetic response due to the ...

Evolution of Neutron Star Magnetic Fields

open access: yesUniverse, 2021
Neutron stars are natural physical laboratories allowing us to study a plethora of phenomena in extreme conditions. In particular, these compact objects can have very strong magnetic fields with non-trivial origin and evolution.

Effect of Protoneutron Star Magnetized Envelops in Neutrino Energy Spectra

open access: yesParticles, 2022
The neutrino dynamics in hot and dense magnetized matter, which corresponds with protoneutron star envelopes in the core collapse supernova explosions, is considered.

Properties and Composition of Magnetized Nuclei

open access: yesParticles, 2020
The properties and mass distribution of the ultramagnetized atomic nuclei which arise in heavy-ion collisions and magnetar crusts, during Type II supernova explosions and neutron star mergers are analyzed.

Long-duration Gamma-Ray Burst Progenitors and Magnetar Formation

open access: yesThe Astrophysical Journal, 2023
Millisecond magnetars produced in the center of dying massive stars are one prominent model to power gamma-ray bursts (GRBs). However, their detailed nature remains a mystery. To explore the effects of the initial mass, rotation rate, wind mass loss, and

Solving the Mystery of Fast Radio Bursts: A Detective’s Approach

open access: yesUniverse, 2023
Fast radio bursts (FRBs) are still a mystery in contemporary astrophysics. Unlike many other astronomical objects whose basic physical mechanism is already identified and the research on which focuses mainly on refining details, FRBs are still largely ...

Characteristic electromagnetic waves caused by tensorial and possible nontensorial thermal high-frequency gravitational waves from magnetars

open access: yesNuclear Physics B, 2019
Interaction between the gravitational waves (GWs) and the strong magnetic fields would lead to the perturbed electromagnetic waves (EMWs). Magnetars can have ultra-strong surface magnetic fields ∼1011Tesla, and meanwhile, they would generate the thermal ...

The strongest magnetic fields in the universe: How strong can they become?

open access: yesFrontiers in Physics, 2014
Magnetic fields in the universe are in general weak, of the order of µGauss only. However, in compact objects they assume extraordinarily large values. These are produced by gravitational collapse of massive magnetised objects.

Zeeman Splitting of Torsional Oscillation Frequencies of Magnetars

open access: yesUniverse, 2023
Magnetars form a special class of neutron stars possessing superstrong magnetic fields and demonstrating power flares triggered by these fields. Observations of such flares reveal the presence of quasi-periodic oscillations (QPOs) at certain frequencies;
